APPARATUS FOR LIGHTING GAS BY ELECTRICITY.

SPECIFICATION formingpart of Letters Patent No. 234,662, dated November 23, 1880.

Application filed July 23, 1880. (No model.)

To all whom it may concern:

Be it known that I, EDWARD N. DICKERSON, J r., of the city, county, and State of New York, have invented a new and useful Improvement in Apparatus for Lightin g Gas by Electricity, of which the following is a full, true, and exact description, reference being had to the accompanying drawing.

Hy apparatus relates to that class of burners lighted by electricityin which each burner is lighted separately by a hand-pull or equivalent mechanism. ln these burners a movable electrode is caused to traverse or come in conthese electrodes'past each other, in combination with a suitable battery and coil situated elsewhere, produces the lighting-spark.

Myinvention will be readily understood from the accompanying drawing, in which E represents a gas-burner; A, the fixed electrode; 0, the movable electrode, which rises and falls by moving electrode slides in groovesor channels or equivalent devices attached to the burner B, and it is drawn down by the spring E, attached to the pin H on the electrode, and at the opposite end to a pin, I, on the burner. The cord D is attached likewise to the moving electrode and passes over'a pulley or pin, 1*, and it may be guided by a ring, G, attached to the fixed portion of the burner.

By pulling the cord D the electrode 0 is I drawn up so that the spring K, attached to its upper extremity, comes in contact and springs I past the fixed electrode A. On releasing the cord the spring E retracts the movable elec- I trode to the position shown in the drawing.

The advantages of this arrangement are obvious. The spring-electrodeKin its ordinary position is below the gas-flame, and not in a position to be injured by the heat of such flame. The electrode may be operated at any moment without turning ofi' the gas or interfering with the passage of the latter through the burner.

In a simpler form of this apparatus the movable electrode might be elevated by the spring and depressed by the cord; but this is not so advantageous, since the point of the movable electrode is liable to be affected by the heat of the flame.

I am aware of the use of vibrating electrodes and of vertically-sliding electrodes arranged to be operated by the turning of the cock, both of which constructions are attended with disadvantages, the first being unsuitable t'or use where the burner is employed with a narrow chimney, and the latter necessitating the full turning on ofthe gas prior to igniting, pret'enting any modification ot' the flow until the spark is secured, and rendering it necessary to furnish acock with each burner.

My device is applicable to and effective with the burner alone, and may be employed with the ordinary fixtures.

What I claim as my invention, and desire to secure by Letters Patent, is-

A gas-burner in which are combined, as set forth, a pillar, fixed electrode, vertically-guided movable electrode, a spring arranged to depress the latter, and cord and appliances wherei by the said movable electrode may be elevated by means of the cord, substantially as described.
